Abstract

Cryosurgery is a procedure in which diseased tissue is destroyed by freezing. During a strictly controlled process, lowtemperature is used to separate diseased from healthy tissue with minimal bleeding. It is an effective method that has beenapplied in many areas of medicine for a number of years, especially in dermatology, oncology, laryngology, gynecology,vascular surgery and ophthalmology. There are many technical solutions—different probes—for applying low temperature totissue. The detailed construction of the probes are trade secrets and will not be discussed here. In the paper the authorspresent the results of research on a chosen type of cryosurgical probe for various conditions: feeding gases, flow rates andexternal conditions. The results are illustrated in the form of graphs showing the temperature of the tip of the probes inchanging conditions.
